Training at work

I dreamt I was at work taking a training class with my love interest/coworker William and the secretary Ms Virginia was facilitating the training. When the class was over I noticed a burgundy color ink or paint on the white floor so I cleaned it up and wipe my hands, however I can still see a faint stain remaining. William left the classroom ahead of me to go to our next training class. When I left the classroom I contemplated taking a different way to the next training but thought that way would be longer so I decided to go the way William went and try to catch up with him. I reached the next classroom and meet William at the door. We stood at the doorway together not entering the classroom for some reason. I saw there were other men sitting on the class and also one of our adolescent patients Derrick sitting on the floor in the middle of the walkway. I’m looking at Derrick wondering why is he in our training class and Derrick proceeds to say to me “what you looking nigga.? However, I didn’t respond and William stood next to me quietly that’s what a black man who was teaching the class. Said “this man’s wife is not a nigga, she’s nothing like that. Then another guy tried to interject and the teacher continued to defend me and said “no, because you have to know people and she’s not like that. And that’s all I remember.
